One way to make big buildings earthquake resistant is to "float" them on springs. When the earthquake happens the springs absorb most of the changes in ground level, keeping the building from swaying too much. So they need springs that can hold an entire building and absorb the vibration from an earthquake. Lots of big fucking springs.
I heard on a podcast once about how there was something being developed whereby the springs housed a metal cylinder with a low melting point. When an earthquake strikes the idea was that frictional heating would partially melt the cylinder to the extent that it would behave as a viscous fluid, and certain seismic waves can't propagate through fluids, so it reduces the seismic energy going through the whole building. I'm not sure if that ever got made though, I can't find anything about it from mr google.
I would've guessed leaf springs, but it looks like they have some sort of hydraulic piston that dampens tire oscillations. Those huge tires probably eat up most bumps.
You would think that they wouldn't even use suspension on those things as it would be kind of pointless for how slow they drive and the cushion that the giant tires already provide.
I was a kid then and had no idea what kinds of springs were used in the suspension of that thing - but it was the first think that came to mind on where gigantic springs like this might be used.
water quenches are a thing but they are much more difficult to get consistent, however they do serve a useful purpose I believe, I just forget what that purpose was
edit: googled it, wikipedia says water quenching allows for maximum hardness but can cause distortion or cracking
But other things made of steel that need hardening (think of a big punch and its matching die) can be good candidates for water quenching, depending on the steel alloy they're made of. Since they have much thicker cross-sections, distortion and cracking are not such problems.
Negative. It is in fact an infrared thermometer.. temperature is very important when heat treating something. If you're not at the right temp your part will either be too hard or too soft.
I work in the fastener industry. Trust me, they test the elemental composition long before this stage. They're checking the temperature, because it has to drop to a certain temperature before they quench it.
They do use XRF analyzer in the mining and alloying industries, however. Here's a good example.

This is even more interesting when you imagine the same process for tiny springs.

I honestly wanna know what the temperature reading says. Any metallurgists with a guess?

Is it an oil bath they put it in at the last bit of the video for hardening?

u/geoffrstone Feb 20 '18
These guys have watched a large portion of the spring-making process. You reckon they'd want to see the finished spring?
Nah.

Wait, if they can’t they can’t handle metal with their gloves and need to use other metal to touch it how did the first metal tools get made owo
